UNITED STATES FRANK SIMEK, OF GENEVA, GHID.

ROAD SGRAPER.

Application filed. May 14, 1925. Serial No. 30,186.

To all whom t may concern:

Be it known that I, FRANK SIMEK, a citizen of Czechoslovakia, residing at Geneva, in the county of Ashtabula, and State of Ohio, have invented certain new and useful Improvements in Road Scrapers, of which the following is a specification.

This invention relates to improvements in road scrapers.

The primary object of the invention is to provide a road scraper of the wheeled scoop type wherein the scoop may be manipulated to arrange it in a load gathering position and, after receiving the load, it may be shifted for preventing additional matter from entering the scoop while the load is being carried to its point of destination, whereupon the scoop may be tilted for discharging the load.

A further object of the invention is to provide a tail gate for the scoop which will be locked in its closed position during the gathering and transporting of` a load and will be automatically iuilocked or released when the scoop is tilted for discharging the load. y

@ther objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Figure l is a side elevational view of the scoop embodying this invention, the scoop being shown in its load gathering position, e Figure 2 is a similar view to Fig. 1, but shows the scoop being tilted to discharge the load.

Figure 3 is a top plan view of the road scraper structure illustrated in Figs. 1 and 2,

\ Figure 4 is a vertical sectional view taken upon lines lV-IV of Fig. 1,

Figure 6 is a vertical sectional view showing a fragmentary portion of the structure illustrated in Fig. 5 and shows the scoop operating lever shifted into a position for holding the scoop against movement,`

Figure 7 is a vertical sectional view taken upon line VIL-VH of Fig. 5, and

Figure 8 is a detail perspective view of a fragmentary portion of the tail gate for the scoop and illustrates a part of the tail gate actuating mechanism.

ln the drawings, wherein for the purpose of illustration is shown a preferred embodiment of this invention, the numeral 5 designates an inverted ti-shaped cross bar having the trunnions or axles 6 projecting laterally outwardly from the opposite sides of the same and havingrotatably mounted thereon the ground engaging wheels 7. Rigidly fastened to the side arms of the U-shaped cross bar 5 is a horizontally extending, forwardly opening U-shapcd frame portion 8 having pivotaliy connected adjacent the free ends of the side arms of the same the depending links 9 which have pivotally connected to their lower ends the opposite sides of the scoop l0. The links 9 have further pivotally connected to their lower ends the forwardly extending, rearwardly opening yoke 11 which has an eye 12 formed in its outer portion to which a whiifle-tree or other suitable draft connector element 13 may be connected for permitting horses, a tractor, or other suitable power unit to .be attached to the scraper for pulling the latter. The forward upper corners 14 of the scoop 10 have pivotally connected thereto the links 15 which are pivotally and slidably connected at their upper ends to theextreme free ends of the side arms of the frame 8 by the bolt and slot constructions 15.

ltigidly fastened to the side portions of the yoke 11, forwardly of the forward end of the scoop 10, is a cross brace member 17 which is in the form of a heavy strap bent at spaced points into inverted U-shaped bearing portions 18 which extend perpendicularly in parallelism. Journaled in axially alined openings in these bearing portions 18 is a transverse shaft 19having arms 20 fastened toits opposite ends. Pivotally connected to the free ends of these arms 2O are links 21 which extend downwardly and are pivotally connected to the forward, lower corners 22 of the scoop 10. This rock shaft 19 has rigidly fastened thereto a substantially rectangularly-shaped arm 23 which has formed integrally therewith at its free end an ear 2li which is suitably apertured for receiving the pin or bolt 25. This pin or bolt 25 passes through a longitudinally extending slot 2G formed in the actuating lever 27. This lever 27 is pivotally connected at its lower end 28 to a second rock shaft 29 journaled in suitable openings in the bearing portions 18 and extending in parallelism with the first mentioned rock shaft 19. This lever 27 is pivotally mounted upon the rock shaft 29 and is allowed to move longitudinally in respect thereto between the movement limiting collars 30 rigidly carried by the said shaft. The bolt or pin 25 is clearly illustrated in Fig. 6 as being of a suitable length to permit this lever 27 to shift in respect to the shaft 29 and the arm 23. This shifting of the lever 27 is to permit the lateral iange 31 carried by the same to be moved into and out of engagement with the teeth 32 carried by the rack 33 which is suitably fastened ,at its opposite ends to one side of the yoke 11 and the cross brace 17, the said rack being of substantially inverted U-shape.

It will now be seen `that by moving the lever 27 out of engagement or out of the path of the teeth 32, the lever may be pivoted or rocked for raising or lowering the front portion of the scoop 10 which rocks or pivots upon the lower ends of the links 9. By shifting the flanged portion 31 of the lever 27 into engagement with any desired one of the. teeth 32, the scoop 10 may be held in any of its shifted positions. The scoop 10 has a tail gate 34 pivotally connected at its upper longitudinal edge to the upper, rear corners 35 of the scoop. This tail gate 34 is clearly illustrated in Fig. 8 'as havingfastened thereto a laterally projecting arm 36 which is bent upwardly to form the portion 37 which is apertured at 38 in alinement with the fulcrum line of the tail gate and is pivotally mounted upon the same supporting rod 39 as supports the tail gate. This perpendicularly extending portion 37 has formed therewith a forwardly and upwardly extending arm 40 which is shown in Figs. 1 and 2 as having its outer end 40a underlying one side portion of the substantially U-shaped frame 8.

The adjacent side wall of the scoop 10 has pivotally fastened thereto the bellcrank-shaped latch 41 which has its hooked portion 42 arranged to engage the free portion of the arm 36, carried by the tail gate 34, for maintaining the said gate in its closed position. The free end 43 of the second arm of the bell-crank-shaped latch 41 is slightly curved and underlies the angular portion 44 of themember 40 carried by the tail gate 34 The trunnions 6, carried by the cross bar 5, have pivotally fastened thereto the forwardly extending side bars 45 which have bolt and slot connections with the cross brace 17 at the points at which the opposite ends of the same are fastened to the sides of the yoke 11. One of these side bars 45, i e., the side bar located on the same side as the latch 41 is located, is provided with a depending, apertured ear 46 to which is )ivotally connected the bell crank lever 47.

he free end of one of the arms of this lever 47 has pivotally connected thereto a link 48 which is pivoted at its opposite end to the free end of an arm 49 adjustably carried by the adjacent side of the frame 8 and depending therefrom. The free end of the remaining arm of this bell-crank-shaped lever 47 has connected thereto a rod 50 which is pivotally connected at its free end to the rock arm 51 carried by the adjacent end of the rock shaft 29. This rock shaft 29 is provided with an arm 52 that is slidably received within an aperture 53 formed in the ear 54 carried by the bar 23 which is rigidly fastened to the rock shaft 19. lt will now be seen that when the lever 27 is moved downwardly along` the rack 33 to elevate the front end of the scoop 10, the rock shaft 29 will be moved or rotated, due to the connection of the member 52 within the arm 23, which rotation will cause the rock arm 51 to move upwardly for drawing upon the rod 50. This movement of the rod will rock the bell-crank-shaped lever 47 for pulling downwardly upon the rear portion of the frame 8. This downward pull upon the frame 8 will cause the cross bar 5 to swing rearwardly upon the supports provided by the trunnions 6 and ground engaging wheels 7. This downward movement of the rear portion of the frame 8 will cause the end 40a of the arm 40 to be engaged and to be pushed downwardly upon the curved end 43 of the latch 41. This movement of the arm 40, due to its pivotal connection at 39 with the scoop 10, will cause the tail gate 34 to swing open, the engagement between the arm 40 and the arm 43 of the latch 41 causing` the latch to pivot for unlocking the said gate.

It will now be apparent that when the scoop 1() is in the position illustrated in Fig. 1, the scoop will function as a scraper. After the scoop has been loaded, it may be rocked slightly for elevating the front end of the same. The scraper may then be moved to the point where the load is to be dropped. After arriving at this place, the lever 27 may be moved along the rack 33 for tilting` the scoop 10 and at the same time unlocking and opening the tail gate 34. The load in the scoop will thereby be discharged.

lt is to be understood that the form of this invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.
